Healthletic Methylene Blue Review 2026: 7 Options Compared

Published: October 2, 2026 · Last updated: October 2, 2026 · By NooBlue Editorial · 7 products compared · About our editorial standards

Two different companies sell a product called Ultimate Methylene Blue, and that causes real confusion at checkout. Healthletic methylene blue is a 1% liquid in a 30 mL dropper bottle, sold from the brand’s own store at healthletic.io. NooBlue, the company that publishes this page, sells Ultimate Methylene Blue Capsules and a 1% solution under a similar name. We read Healthletic’s product pages on October 2, 2026, wrote down every price and dose they print, and compared them with six other products you can order today.

A plain disclosure before the numbers: NooBlue makes three of the seven products ranked here, and our gummy holds the #1 spot as our own pick. Every other position follows a rule you can check for yourself, which we explain in the methodology section. Where a brand page left out a figure we needed, we say so and leave the cell empty.

Short answer for searchers: Healthletic methylene blue is a USP grade 1% solution (10 mg per mL) in a 30 mL bottle, priced at $32.99 for one bottle on October 2, 2026, which works out to about $1.10 per 10 mg before any subscription or bundle discount.

Healthletic Methylene Blue at a Glance

Healthletic’s main methylene blue product is the Ultimate Methylene Blue 1% solution in a 30 mL (1.0 oz) bottle. The store also lists Ultimate MB Capsules + Vit. C and a few promotional versions of the liquid.

On the liquid page, one bottle is $32.99 as a one-time purchase. A subscription drops that to $24.99 per bottle. The bundle offers are two bottles for $59.90 and a buy-two-get-one deal at $69.90 for three bottles. Our table uses the one-time single-bottle price.

Healthletic’s page says the product is USP grade and 99.9% pure, heavy-metal free, and third-party tested for identity, purity and heavy metals. It says each batch has a certificate of analysis and that bottling happens in quality-controlled cGMP facilities with batch traceability. A button on the page opens an image of lab results. The page text does not name the testing lab or give a lot number, so we could not tie a report to a specific batch. If that matters to you, our guide to reading a methylene blue certificate of analysis line by line shows which fields to ask for.

The page also states a 30-day money-back guarantee and prints a safety note to avoid methylene blue with SSRIs and SNRIs. We agree with that warning and explain the reason further down. Customer-count claims appear near the price box, and the liquid and capsule pages print two different totals. We had no way to verify either number, so neither one affects the ranking.

For a wider view of the market before you narrow it down to one brand, our full ranking of methylene blue supplements covers more products and every common format.

Two Products Called Ultimate Methylene Blue

Search “ultimate methylene blue” and you can land on either brand. Here is how to tell them apart before you pay.

• Healthletic Ultimate Methylene Blue: a 1% liquid in a 30 mL dropper bottle, sold at healthletic.io. Healthletic also sells a capsule called Ultimate MB Capsules + Vit. C.
• NooBlue Ultimate Methylene Blue Capsules: 5 mg capsules, 60 per bottle, sold at nooblue.com.
• NooBlue Ultimate Methylene Blue Solution 1%: a 1% liquid in a 50 mL bottle, also sold at nooblue.com. The product page calls it NooBlue Methylene Blue Drops.

So a 1% liquid with “Ultimate” on the label could be either company’s product. Check the volume first. Healthletic’s bottle holds 30 mL and NooBlue’s holds 50 mL. Then check the seller domain on your order confirmation. Fake and relabeled bottles are a known problem with this compound, and our checklist on what genuine methylene blue packaging should look like covers seals, batch codes and label details worth photographing when the parcel arrives.

Healthletic Methylene Blue vs 6 Alternatives: Comparison Table

Every price below was read from the brand’s own store on October 2, 2026, as the single-unit price before shipping and before any subscription. The cost column divides that price by the total milligrams of methylene blue in the pack and multiplies by 10. Every row uses that same unit, so you can compare a gummy, a capsule, a troche and a liquid on one line.

Why is the cheapest product at #2 and not #1? Our own gummy sits at #1 as our pick. Positions #2 to #5 are the four liquids, because a liquid is what Healthletic sells and what most people searching its name want to compare. Within that group the order is verified price per dose at 10 mg, lowest first. Positions #6 and #7 are the fixed-dose formats, again ordered by cost.

The Seven Products, Reviewed One by One

Each entry below lists the specs we read on the product page, the pros and cons we found, and who the product suits. Prices are the single-unit prices from October 2, 2026. NooBlue prices update automatically from our store.

#1. NooBlue Methylene Blue Gummies — Best for most readers (our pick overall)

Key specs: 10 mg USP grade methylene blue and 25 mg vitamin C per gummy, 60 gummies per bottle, zero sugar, pectin base, Wild Blueberry flavor. Price $49.99 for 60 gummies, which is $0.83 per 10 mg at today’s price.

A liquid asks you to measure, dilute and rinse. The gummy asks you to eat one. Each one is precisely dosed at 10 mg, so the number you take matches the label every day.

The vitamin C does a specific job. It reduces methylene blue to leucomethylene blue inside the gummy, so the gummy arrives already reduced and electron-loaded. That form is colorless by chemistry and has a more lipid-soluble character than the oxidized blue form. In practice that means no blue-mouth mess from the gummy itself, although no product can promise a stain-free outcome for every person. The purple color you see comes from blueberry extract.

NooBlue publishes a CTLA COA for the gummy on the product page, which names the lab that ran the analysis. That is the document most buyers never get from a marketplace gummy. If you want the background on why the gummy format works differently from a dropper, our guide to methylene blue alternatives and formats compares each delivery method side by side.

Pros:

• Fixed 10 mg per gummy, so there is no dropper math
• Arrives already reduced, with no blue-mouth mess from the gummy
• Zero sugar and a published CTLA COA
• Free worldwide shipping over $100

Cons:

• Costs more per 10 mg than the cheapest 1% liquid in this list
• A fixed 10 mg serving, so a 5 mg starting step means the capsule instead
• A smaller brand with fewer marketplace reviews than the big Amazon sellers

Best For: Anyone who wants a measured daily amount without a dropper, and anyone who has tried a liquid and disliked the mess.

#2. Nutricel Blue Liquid 1% — Best for the lowest verified cost per 10 mg in this list

Key specs: 1% methylene blue in purified water (10 mg per mL), 120 mL bottle, 0.05 mL graduated dropper, alcohol-free, amber plastic bottle, made in the USA. Price $30.00 for 120 mL, which is 1,200 mg of methylene blue, or $0.25 per 10 mg.

On raw price per milligram, nothing else in this comparison comes close. One Nutricel bottle holds four times the volume of a Healthletic bottle for slightly less money. The page is also unusually specific. It prints the dropper volume, a drops-to-milligrams chart and the solvent, and it says the raw material certificate of analysis reports 99.4% methylene blue content.

There are trade-offs. The bottle is plastic where most competitors use glass. Nutricel’s page says certificates of analysis for its capsule formulas are published on its certificates page, while the liquid relies on a signed manufacturer attestation and the raw material COA. We compared Nutricel’s capsule line with ours in our Nutricel vs NooBlue methylene blue comparison, including the dose and vitamin C differences.

Pros:

• $0.25 per 10 mg, the lowest verified cost in this list
• Prints the dropper size and a drops-to-mg chart
• Alcohol-free, made in the USA

Cons:

• Plastic bottle
• No lot-specific COA for the liquid in the page text we read
• A liquid still means measuring and possible staining

Best For: Price-focused buyers who are comfortable measuring a liquid and want the most milligrams per dollar.

#3. NooBlue Methylene Blue Drops 1% — Best for a larger 1% bottle at about half Healthletic’s cost per mg

Key specs: 1% USP grade methylene blue solution (10 mg per mL), 50 mL bottle with a glass dropper, 500 mg of methylene blue per bottle. Price $29.99, which is $0.60 per 10 mg at today’s price. The product page suggests about 0.5 to 1 mL mixed into water or juice once daily with food.

This is the closest NooBlue match to the Healthletic liquid. Both are 1% solutions, so 1 mL holds 10 mg in either bottle. The differences are size and price. NooBlue’s bottle holds 50 mL against Healthletic’s 30 mL, and the cost per 10 mg is $0.60 against $1.10 on a single-bottle order.

The page states that every batch is third-party tested for purity and heavy metals and links the published ingredient analysis. A liquid gives you the finest dose control in this list, which suits people who want to adjust in small steps. Our walkthrough on how to take methylene blue drops covers measuring, diluting and rinsing in detail.

Pros:

• Lowest cost per mg among NooBlue products
• Glass dropper and a 50 mL bottle
• Finest dose control, verified COA and third-party tested

Cons:

• Costs more per mg than the Nutricel liquid
• Liquid methylene blue can stain cups, counters and teeth

Best For: Liquid users who want to adjust their amount in small steps and want a bigger bottle than Healthletic sells.

Shop Liquid: NooBlue Methylene Blue Drops 1%

#4. Healthletic Ultimate Methylene Blue 1% — Best for buyers who will stay on a subscription

Key specs: 1% methylene blue (10 mg per mL), 30 mL bottle, 300 mg of methylene blue per bottle. Price $32.99 for one bottle as a one-time purchase, or $24.99 per bottle on subscription. That is $1.10 per 10 mg on a single order and $0.83 per 10 mg on subscription.

Healthletic’s liquid is a reasonable product with a clear purity claim, a USP grade statement and a 30-day money-back guarantee. Its weak spot is price on a first order. At $32.99 for 30 mL, a single bottle costs nearly twice as much per milligram as NooBlue’s 50 mL solution and more than four times as much as Nutricel’s 120 mL bottle. The subscription closes much of that gap, so the brand makes the most sense for someone who already knows they will reorder.

The dosing section is worth reading slowly. It suggests starting at 5 to 6 drops a day and says each drop is about 0.25 mg. It then gives a typical range of about 5 to 19 mg a day at 20 to 30 drops. Those two figures do not match each other. At 0.25 mg per drop, 30 drops would be 7.5 mg. Nutricel’s spec sheet works from the more common figure of about 0.5 mg per drop for a 1% liquid. Our advice is to measure by volume with a marked dropper or oral syringe, where 0.5 mL of any 1% solution is 5 mg.

Pros:

• USP grade and 99.9% purity claim with a lab-results image
• 30-day money-back guarantee
• Subscription price of $0.83 per 10 mg

Cons:

• $1.10 per 10 mg on a one-time order
• Drop-to-milligram guidance on the page does not add up
• No lab name or lot number in the page text

Best For: Buyers who like the brand, will commit to a subscription and are happy to measure by millilitre.

#5. Meraki Blu 150 mg Liquid Drops — Best for a half-strength liquid

Key specs: 150 mg of USP grade methylene blue in a 30 mL bottle with a 1 mL dropper, which works out to 5 mg per mL (0.5%). Price $35.00 for one bottle, or $2.33 per 10 mg.

Meraki Medicinal’s liquid is half the strength of the other three liquids here. That has one practical upside: a full 1 mL dropper delivers 5 mg, which is an easy starting amount to measure. The downside is cost. At $2.33 per 10 mg it is the most expensive liquid in this comparison by a wide margin.

The page says every batch is lab-verified and tested for heavy metals and impurities. It also carries the line “For research purposes only,” next to warnings about age, pregnancy and antidepressants. Buyers should read that wording and decide for themselves what it means for a product sold as a supplement. We looked at the brand in more depth in our Meraki methylene blue review.

Pros:

• One full dropper equals 5 mg
• Batch testing for heavy metals stated on the page

Cons:

• $2.33 per 10 mg, the priciest liquid here
• “For research purposes only” wording on the product page

Best For: People who want a lower-strength liquid where one dropper is a small, simple amount.

#6. NooBlue Ultimate Methylene Blue Capsules — Best for starting low at a fixed 5 mg

Key specs: 5 mg USP grade methylene blue per capsule with vitamin C, 60 vegetable-cellulose capsules per bottle, 300 mg per bottle. Price $37.99, which is $1.27 per 10 mg at today’s price.

These are the capsules that share a name with Healthletic’s liquid. They suit a different buyer. A 5 mg capsule is the simplest way to begin at a low, fixed amount, and it keeps the dye inside a shell until it is swallowed. You can start here and move up to the 10 mg gummy once you know how you respond.

Per milligram the capsules cost more than either NooBlue liquid, because you are paying for the encapsulation and the convenience. The page links the published ingredient analysis. For a straight comparison of the two NooBlue formats, read whether NooBlue capsules beat the liquid solution for your routine.

Pros:

• Fixed 5 mg dose, ideal as a first step
• No measuring and no liquid on your tongue
• USP grade with a published ingredient analysis

Cons:

• $1.27 per 10 mg, more than the NooBlue liquid
• Higher daily amounts mean more capsules

Best For: First-time users who want a small, fixed dose with no dropper.

#7. Troscriptions Just Blue — Best for a scored troche you can split

Key specs: 16 mg methylene blue per ingestible troche, 4 troches per pack, and the page says each pack holds up to 16 doses. Price $27.00 per pack, which is 64 mg of methylene blue, or $4.22 per 10 mg.

Troscriptions sells a dissolvable troche, a format none of the other products here use. The troches are scored, which is how a 4-troche pack stretches to 16 doses. The brand states USP grade purity, third-party lab testing, a cGMP facility and US manufacturing. Its certificate of analysis is available on request through a form on the product page.

Cost is the clear drawback. At $4.22 per 10 mg it is the most expensive product in this comparison. Our Troscriptions methylene blue review covers the full troche range.

Pros:

• Scored troche that splits into smaller doses
• COA available on request

Cons:

• $4.22 per 10 mg, the highest cost here
• Only 4 troches per pack

Best For: People who specifically prefer a dissolvable troche and do not mind paying for it.

Also considered, not ranked

Healthletic also lists Ultimate MB Capsules + Vit. C on its store at $25.00, shown against a crossed-out $49.00. The page text we read did not state the milligrams per capsule or the capsule count, so we could not work out a cost per 10 mg and left it out of the ranking.

How We Evaluated These Methylene Blue Products

We started from Healthletic’s own product line and added the products a Healthletic shopper is most likely to weigh against it. For every product we opened the brand’s own store page on October 2, 2026 and recorded five things.

• Purity grade as stated: whether the page claims USP grade or pharmaceutical grade methylene blue, and any purity percentage it prints.
• Lab paperwork: whether a certificate of analysis is shown, linked, published or only available on request, and whether the page names the lab.
• Price per 10 mg: the single-unit, one-time price divided by the total milligrams in the pack, times 10.
• Format: gummy, capsule, troche or liquid, plus strength for liquids.
• Warnings and guarantees: the interaction warnings and refund terms the page prints.

The order follows a simple rule. Our gummy is #1 as our own pick. The four liquids come next because Healthletic sells a liquid, ranked by price per 10 mg. The two fixed-dose products follow, also ranked by price per 10 mg. We did not lab-test any product, and we did not use star ratings or customer counts, because we could not verify them. Our Better Life Labs methylene blue review ranks a different set of products on cost alone, if you want a second view.

Dropper Math: Milliliters to Milligrams for Each Liquid

Drop size varies, so a marked dropper or oral syringe is more reliable than counting. This table converts volume to milligrams for each liquid in this review, using the strength each brand prints.

The point of the table is the bottom row. Swap from a 1% liquid to Meraki’s 0.5% liquid at the same volume and you take half as much methylene blue. Swap the other way and you double it. Always check the strength on the label when you change brands, and start again at a low amount.

Healthletic vs NooBlue Liquid: Side by Side

On a first order the NooBlue bottle gives you two-thirds more methylene blue for less money. Healthletic’s subscription narrows the gap to $0.83 per 10 mg, which is still above NooBlue’s one-time figure of $0.60. If you already prefer Healthletic’s brand, the subscription is the way to buy it.

What the Research Says About Low-Dose Methylene Blue

Human research on low-dose methylene blue is still small, and most of the mechanism work comes from cells and animals. One human trial stands out for this kind of product. In a randomized, double-blind, placebo-controlled study of 26 healthy adults published in Radiology, a single low oral dose of methylene blue increased brain activity on functional MRI during attention and short-term memory tasks one hour later, and it was linked to a 7% increase in correct answers during memory retrieval (Rodriguez et al., 2016).

That is one small trial measured over one hour, so it may support the idea of short-term cognitive effects without telling us what daily use does over months. Studies suggest a mechanism tied to mitochondrial electron transport, which is why products in this category talk about energy and focus. None of the brands in this review, including NooBlue, can point to a trial of its own finished product.

Who Should Check With a Doctor First

Methylene blue has one interaction that every buyer should know about. Laboratory work on purified human enzymes published in the British Journal of Pharmacology showed that methylene blue is a potent, reversible inhibitor of monoamine oxidase A (Ramsay et al., 2007). The authors concluded this explains the serotonin toxicity seen when the compound is given to people taking SSRIs. That is why Healthletic, Nutricel and Meraki all print antidepressant warnings, and we give the same advice here.

Talk to your doctor before you start if you take an SSRI, SNRI, MAOI or any other serotonergic medicine, if you are pregnant or nursing, or if you take prescription medicines of any kind. Our page on methylene blue side effects lists the common, mild effects such as blue-green urine, and the warning signs to stop and get help.

Healthletic Methylene Blue FAQ

Is Healthletic methylene blue legit?

Healthletic Ultimate Methylene Blue is a real 1% USP grade product sold from the brand’s own store at healthletic.io, with a 30-day money-back guarantee. Its page shows a lab-results image, but the page text does not name the lab or a lot number. Ask the brand for a lot-matched certificate of analysis before you buy.

How many drops of Healthletic methylene blue equal 5 mg?

Measure 0.5 mL of Healthletic Ultimate Methylene Blue to get 5 mg, because the liquid is 1% strength. The page says each drop is about 0.25 mg but also gives a range that does not match that figure. Drop size varies, so a marked dropper or oral syringe is more reliable than counting drops.

What is the best methylene blue supplement?

NooBlue Methylene Blue Gummies is our pick, with a precisely dosed 10 mg of USP grade methylene blue, zero sugar and a published CTLA COA. If you want a liquid, NooBlue’s 1% Drops cost $0.60 per 10 mg. The Nutricel 1% liquid has the lowest verified cost per 10 mg in this comparison.

Healthletic vs NooBlue: which Ultimate Methylene Blue is which?

Healthletic Ultimate Methylene Blue is a 1% liquid in a 30 mL bottle. NooBlue Ultimate Methylene Blue Capsules are 5 mg capsules, and NooBlue’s Ultimate Methylene Blue Solution is a 1% liquid in a 50 mL bottle. Check the bottle size and the seller on your order to know which one you have.

How much does Healthletic methylene blue cost per milligram?

Healthletic Ultimate Methylene Blue costs $1.10 per 10 mg on a single $32.99 bottle, read on October 2, 2026. On the $24.99 subscription price it falls to $0.83 per 10 mg. NooBlue’s 1% Drops cost $0.60 per 10 mg on a one-time order.

Can you take methylene blue with antidepressants?

Healthletic, Nutricel and Meraki all print warnings against combining methylene blue with SSRIs or SNRIs, and we give the same advice. Methylene blue inhibits monoamine oxidase A, which can lead to serotonin toxicity alongside these medicines. Speak to your doctor before taking it with any prescription medicine.

Where can I buy Healthletic methylene blue?

Healthletic Ultimate Methylene Blue is sold on the brand’s own store at healthletic.io. Buying direct from the brand or from NooBlue’s store at nooblue.com is the safest way to avoid relabeled bottles. Check the seller name and the batch code when the order arrives.

The Verdict

For most people comparing Healthletic methylene blue, NooBlue Methylene Blue Gummies is the clear winner because it removes the measuring step, arrives already reduced with no blue-mouth mess, and costs $0.83 per 10 mg with a published CTLA COA. If you want a 1% liquid like Healthletic’s, go with NooBlue’s 50 mL Drops at $0.60 per 10 mg, which is a little over half the cost of a single Healthletic bottle. Budget pick: the Nutricel 1% liquid at $0.25 per 10 mg, if you are happy with a plastic bottle and a big volume.

Healthletic’s own liquid is a fair product with a clear purity statement and a refund window. If you like the brand, buy it on subscription and measure in millilitres.
